DOOR-FASTENER.

SPECIFICATION forming part of Letters Patent No. 635,530, dated October24, 1899.

Serial No. 726,651. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES E. DUCK, a citizen of the United States ofAmerica, and a resident of the city of Baltimore, in the State ofMaryland, have invented certain new and useful Improvements inDoor-Fasteners, of which the following is a specification.

This invention relates to door-fasteners which may be used in case of,emergency where there is no bolt or lock to the door or the lock is outof order.

The object of this invent-ion is to provide a simple and convenientdevice of this character which may be portable and can be readilyapplied to serve as a temporary lock for a door as occasion or emergencymay demand.

The invention consists of a door-fastener as hereinafter set forth andclaimed.

Referring to the accompanying drawings, in which similar numerals ofreference refer to like parts, Figure 1 is a view in perspective of aportion of a doorand door-jamb, showing the fastener in locked position.Figs. 2 and 3 are detailed portions of the fastener. Fig. 4 is a planView showing the portions of the door and door-jamb in horizontalsection and the fastener in locked position. Fig. 5 is a modification ofthe invention shown as permanently secured to a door-jamb. A

In carrying out this invention a door fa'stener is provided consistingof two partsa bar which can be secured to the edge of a door-jambbyforcing one end thereof into the door-jamb, the bar extending betweenthe edge of the door and the jamb when the door is closed and projectinginto the room. The other part of the fastener consists of a lockingdevice in the shape of a short arm or bar having one end adapted to bemovable endwise on the bar projecting into the room and also soconnected to said projecting bar as to permit the locking device to betilted thereon and bind on said bar, whereby the locking device acts asa wedging-lever between the door-jamb and the bar projecting into theroom to lock the parts in place and hold the door in locked position.

In constructing the fastener a bar 1, of metal, is employed having atone end a wedgeshaped projection 2, at right angles to the shank or mainportion of the bar 1, and having a sharp edge 3, which is forced intothe wood of the edge of the door-jamb. In conjunction with the bar 1 isemployed a locking device 4, which consists of a short arm 5, preferablycurve-shaped and having an enlarged end or head 6, provided with apassage-way 7 larger than the thickness of the bar 1, so that the head 6can not only be moved freely over the bar 1, extending through thepassage-way 7, but also so that the locking device 4 may be tilted orrocked on the bar 1.

It will be noticed that the ends of the passage-way 7 are provided withedges, the edge 7 of the inner end and the edge 7 of the outer end,diagonally opposed to each other, being brought to bear against thesides of the bar 1 when the locking device 4 is tilted thereon.

The fastener is used as follows: A door 9 being open and the bar 1 beingheld against the door-jamb, the sharp edge 3 of the wedgeshaped end 2 ofthe bar 1 is driven or forced into the door-jamb S by the closing of thedoor and pressing of the edge 3 into the jamb 9, a portion of the bar 1extending between the door and door-jamb and the remaining portionprojecting some little distance out from the inner side of thedoor-jamb, the View in Fig. 1 being on the inside of the door anddoor-jamb. The door being closed, the bar 1 will be wedged between thedoor and the doorjamb, and the wedge-shaped end 2 will be forced intothe door-jamb. The locking device 4 is then slid over the portion of thebar 1 projecting from the door-jamb, the bar 1 extending through theopening 7 in the head 6 and the latter being tilted on the bar 1. As thelocking-piece is pushed inward on the bar 1 the outer end of the curvedportion 5 will be broughtto bear against the side of the door and theedges '7 7" of the passage-way 7 against the sides of the bar 1, and byapplying force the edges 7 and '7 of the passageway 7 will be caused tobind against the bar 1 and the locking device 4 will be firmly wedgedinto place to lock the door and prevent it from being opened from theoutside. The fastener may be released by applying force to thelocking-piece 4 and knocking it backward on the bar 1, therebydisengaging it from its wedged position. The bar 1 may be thendisengaged from the door-jamb and the fastener, composed of two pieces,carried away for future use.

It is obvious that the curved portion 5 of the locking-piece 4 may bestraight instead of curved and extend at an angle to the head 6, thewedging action of the locking-piece still being permissible. The curvedform serves to aid in wedging the locking-piece into locked position.The invention contemplates any construction in lieu of the head 6 andopening 7 whereby the locking device 4 may have a sliding and tiltingand binding connection with the bar 1.

In Fig. 4 I have shown a modification of the fastener which only diifersfrom the construction already set forth in having a portion of the bar 1curved or bent instead of straight. In this form a bar 10 is employedhaving a bent portion 11 so bent as to have one end brought around intocontact with the doorframe. The object of this is to enable the fastenerto be used, if desired, as a permanent bolt or fastener. The bar 10 ispreferably a flat piece of metal which may be bent to the shape 11 inapplying it to the doorframe, and the locking-piece is always at hand onthe bent portion 11, so that the entire fastener may be left permanentlyin place to be used as a door bolt or fastener.

What I claim is 1. A door-fastener, consisting of a bar with an angularprojecting portion at one end adapted to be forced into the edge of thedoorjamb, in combination with a locking device having a head at one end,adapted to engage with and slidable upon said bar, and having a rockingmovement thereon and diagonallyopposed edges adapted to bind on saidbar, with a lever-arm portion adapted to wedge against a door, and locksaid bar in position, as set forth.

2. Adoor-fastener,consisting of a bar adapted to project between theedge of a door and a door-jamb, and having an angular projection at oneend, adapted to be forced into the edge of a door-jamb, in combinationwith a lock ing device consisting of a short curved arm, having asliding and tilting and binding connection with said bar, whereby thelocking device maybe wedged against a door and lock the bar in position,as set forth.

3. A door-fastener, consisting of a bar having a curved or bent portion,the straight portion being adapted to project between the edge of a doorand door-jamb, and having an angular projection at one end, adapted tobe forced into the edge of a door-jamb, in combination with a lockingdevice consisting of a short curved arm, having a sliding and tiltingand binding connection with said bar, whereby the locking device may bewedged against a door and lock the bar in position, as set forth.
